Additive is a kind of conventional way improving Binder Materials hydration activity, is widely used in cement concrete field,
But there is no research report for being specifically designed to the additive improving nickel slag activity.The mineral crystal structure of nickel slag is very fine and close,
The cement additive of triethanolamine series is very faint to the raising effect of nickel slag activity；With the coagulation based on inorganic salts ingredients
Soil early strength agent, volume requires big, and cost is high, affects materials ' durability, and can only improve nickel slag early age strength.Cause
This, study a kind of additive being specifically designed to and improving nickel slag activity index, for raising application level in building materials for the nickel slag
There is positive facilitation.
Content of the invention
The technical problem to be solved in the present invention is to provide a kind of additive improving nickel slag activity index of each age.
In order to solve above technical problem, the invention provides a kind of additive, mainly by organic phospho acid, polyhydric alcohol amine
Nickel slag additive with water composition.First, the organic phospho acid with extremely strong chelation passes through chelant solubilization, promotes
The dissolving of the fine and close mineral constituent in nickel slag top layer, again, nickel slag under the lasting chelation of polyhydric alcohol amine, mineral constituent
Dissolution velocity continues to increase, it is thus possible to improve the hydration rate of nickel slag, reaches to improve the effect of each age nickel slag activity index.
